“Many grand notions and titles have over time attached themselves to this place: a paradise at the southern tip of Africa, the world’s richest floral kingdom, a maritime fulcrum between West and East, a European outpost at the foot of the continent, the Tavern of the Seas. But the two names that are the most potent are also two of the earliest: the contradictory claims of this being both a Cape of Storms and a Cape of Good Hope. The tension between these ideas encapsulates many of the tensions of this city.
Legend has it that the first Portuguese navigator to round the southern tip of Africa, Bartolomeu Dias, named this stormy peninsula Cabo das Tormentas. However, King João II rejected Dias’s name in favour of one that would be more inspirational for the Portuguese people: Cabo da Boa Esperança. The turning point for the Lusitanian caravels would spell untold riches in the East. But the dialectic between the two contending titles is as virile today in a city whose promise is limitless and whose socio-political storms act as a sea anchor.”

"Classical and Baroque Sex in Everyday Life" (1979), Beginning To See the Light: Pieces of a Decade (1981)
Context: There are two kinds of sex, classical and baroque. Classical sex is romantic, profound, serious, emotional, moral, mysterious, spontaneous, abandoned, focused on a particular person, and stereotypically feminine. Baroque sex is pop, playful, funny, experimental, conscious, deliberate, amoral, anonymous, focused on sensation for sensation's sake, and stereotypically masculine. The classical mentality taken to an extreme is sentimental and finally puritanical; the baroque mentality taken to an extreme is pornographic and finally obscene. Ideally, a sexual relation ought to create a satisfying tension between the two modes (a baroque idea, particularly if the tension is ironic) or else blend them so well that the distinction disappears (a classical aspiration).

How to Understand Politics: What the Humanities Can Say to Science (2007)
Context: The simplified notion of self-interest used by our political and social science cannot tolerate the tension between one’s own and the good, for that tension leaves human behavior unpredictable. One cannot penetrate into every individual’s private thoughts, and there is no clear way to judge among different conceptions of the good. So in order to overcome the tension, science tries to combine one’s own and the good in such a way as to preserve neither. It generalizes one’s own as the interest of an average or, better to say, predictable individual who lives his life quantifiably so as to make its study easier for the social scientist. And for the same purpose it vulgarizes the good by eliminating the high and the mighty in our souls (not to mention the low and vicious), transforming our aspiration to nobility and truth into personal preferences of whose value science is incognizant, to which it is indifferent.

Ash-Wednesday (1930)
Context: And the lost heart stiffens and rejoices
In the lost lilac and the lost sea voices
And the weak spirit quickens to rebel
For the bent golden-rod and the lost sea smell
Quickens to recover
The cry of quail and the whirling plover
And the blind eye creates
The empty forms between the ivory gates
And smell renews the salt savour of the sandy earth
This is the time of tension between dying and birth
The place of solitude where three dreams cross
Between blue rocks
But when the voices shaken from the yew-tree drift away
Let the other yew be shaken and reply.

2009, Nobel Prize acceptance speech (December 2009)
Context: There has long been a tension between those who describe themselves as realists or idealists — a tension that suggests a stark choice between the narrow pursuit of interests or an endless campaign to impose our values around the world.
I reject these choices. I believe that peace is unstable where citizens are denied the right to speak freely or worship as they please; choose their own leaders or assemble without fear. Pent-up grievances fester, and the suppression of tribal and religious identity can lead to violence. We also know that the opposite is true. Only when Europe became free did it finally find peace. America has never fought a war against a democracy, and our closest friends are governments that protect the rights of their citizens. No matter how callously defined, neither America's interests — nor the world's — are served by the denial of human aspirations.

1990s, The Rum Diary (1998)
Context: Like most of the others, I was a seeker, a mover, a malcontent, and at times a stupid hell-raiser. I was never idle long enough to do much thinking, but I felt somehow that my instincts were right. I shared a vagrant optimism that some of us were making real progress, that we had taken an honest road, and that the best of us would inevitably make it over the top. At the same time, I shared a dark suspicion that the life we were leading was a lost cause, that we were all actors, kidding ourselves along on a senseless odyssey. It was the tension between these two poles — a restless idealism on one hand and a sense of impending doom on the other — that kept me going.
